PG - 2180-2185 AB - PURPOSE: The long non-coding (lnc) RNAs have been shown to exhibit profound regulatory roles in maintaining the growth and proliferation of human cancer cells. Taking this fact into consideration, the current research work was scheduled to explore the regulatory control of lncRNA-PCAT1 in maintaining the growth and progression of human colon cancer cell. METHODS: The expression of lncRNA-PCAT1 was assessed through qRT-PCR method. DAPI and acridine orange (AO)/ethidium bromide (EB) staining protocols along with the colony formation protocols were performed to evaluate the viability of cancer cells. The migratory and invasion properties of cancer cells were examined by the wound-healing and transwell assays, respectively. Western blotting was used to assess the expression of proteins of interest. MTT assay was used for the assessment of cell proliferation. RESULTS: lncRNA-PCAT1 was highly up-regulated in the colon cancer tissues and cancer cell lines. The repression of lncRNA-PCAT1 in colon cancer cells reduced their viability through induction of Bax/Bcl-2 mediated apoptosis. The inhibition of lncRNA-PCAT1 expression further declined the migration and invasion of colon cancer cells along with the decline of cell proliferation and enhanced the chemosensitivity of colon cancer cells. CONCLUSION: lncRNA-PCAT1 expression may be utilized as a vital prognostic tool in colon cancer and highlighted its regulatory effects in maintaining the colon cancer growth and proliferation.
